摘要：
FIELD: medicine.SUBSTANCE: third positioner with passive markers is installed on the movable part of the pelvic bone. On the X-ray computer tomograph, images of the fixed part of the pelvic bone with a reference positioner with passive markers installed thereon and a movable part of the pelvic bone with the third positioner with passive markers installed thereon are recorded. At the workstation of the X-ray computer tomograph, image processing is performed and a 3D segmented image of the fixed part of the pelvic bone with a reference positioner with passive markers installed thereon and of the movable part of the pelvic bone with the third positioner with passive markers installed thereon, as well as of the fracture region is plotted. The processing results are transferred to the optical medical navigation system computer via the computer network and displayed on the screen to the surgeon for planning and subsequent management of surgical instruments during operation. On the display screen, the surgeon indicates the points of compliance in the fracture region on the 3D segmented image of the fixed part of the pelvic bone and the moving part of the pelvic bone, which, when combining the movable part of the pelvic bone and the fixed part of the pelvic bone during surgery, should be maximally approximated. During the operation using the optical medical navigation system, the reference positioner with passive markers and the third positioner with passive markers installed on the patient and visible by the stereo video cameras of the optical medical navigation system are geometrically linked to the segmented 3D images of the reference positioner with passive markers and the third positioner with passive markers and corresponding segmented fixed portion of the pelvic bone and the movable part of the pelvic bone. During surgery, the moving part of the pelvic bone and the fixed part of the pelvic bone are brought together by "manual" actions and set in the position for subs
